Each controller chassis includes dual controllers equipped with internal components such as a processor, single cache memory module (DIMMs), cache flash memory (CFM), battery, fans. The front of the controller chassis provides a drive bay for loading 2.5-inch or 3.5-inch SAS disk drives.
The controller has an Ethernet connection for out-of-band management using Device Manager - Storage Navigator. If the data path through one controller fails, all drives remain available to data hosts using a redundant data path through the other controller. The controller is equipped with LED indicators for monitoring its operating conditions and notifying possible component replacement.
